No, the plants were gone over very carefully to check for snails. There were none on them. Also, the plants that went into the 135 went in after the plants that went to the L200 tank were moved. So no chance of snails jumping plants.davo;580408;580408 said:can take a while for them to hatch and or establish a presence, you havent had your new plants for that long. those snails ive had before (or something looks identicle) and they never did anything. my yoyos eventually irradicated them
